WebTheory of Freezing Point Depression. Advanced® Osmometers use the industry-preferred freezing point method to determine the osmolality of an aqueous-based solution. When a solute (particles) is dissolved in a solvent (water), the freezing point of that solution is lower than that of the solvent alone. As more solute is added, the freezing ... WebThis is consistent with the freezing point depression formula, as Mg has less mass than Ca. Beyond 24%, CaCl2 is superior. This is because the eutectic point of MgCl2-water is at 21.6 percent, whereas the eutectic point of CaCl2-water is at 30%. The freezing point depression formula is only valid at reasonably low concentrations.

Web2 Purpose The purpose of this is to determine the molar mass of an unknown solute by measuring the freezing point depression of a solvent caused by the solute’s presence.
